Ali has represented Pakistan in a solitary ODI against Sri Lanka in 2012 and was not included in Pakistan’s preliminary 30-man squad for the quadrennial event.
Left arm seamer Junaid Khan was unable to clear a fitness test which put him out of contention for the World Cup starting this month in Australia and New Zealand.
Junaid expressed his disappointment on Twitter but said his well wishes were with the Pakistan team.
Rahat, 26, has 31 wickets from 11 Test matches at 36.67. He recently picked up 4/30 against Lahore Lions playing for the Khan Research Laboratories in Pakistan’s List A cricket.
